I'm looking for a dockable windows/panel control in the style of iGoogle. All of the ones I have found so far all have a fixed length on the height of your window/panel but I want to be able to have windows of varying length like iGoogle.
The best I have found so far has been a control libarary called BlackLight which does not have the feature explained above.
have you seen this docking library:
